1-Aryl-tetrahydroisoquinoline analogs as active anti-HIV agents in vitro
摘要:
A series of 1-aryl-6,7-dihydroxyl(methoxy)-1,2,3,4-tetrahydroisoquinolines (compounds 1-36) were synthesized via Pictet-Spengler cyclization. All the synthesized compounds were assayed for activities against HIV-1(IIIB) in C8166 cell cultures by MTT method for the first time. The results of the anti-HIV screening revealed that 6,7-dihydroxytetrahydroisoquinolines possessed higher selective index than 6,7-dimethoxyl analogs due to the significantly decreased cytotoxicities. Compounds 6, 24, and 36 showed potent anti-HIV activities with EC50 values of 8.2, 4.6, and 5.3 mu M respectively, and the cytotoxicities (CC50) of these three compounds were 784.3, 727.3, and 687.3 mu M, which resulted in SI values larger than 95, 159, and 130 respectively.

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-methyl-3,5-dinitrobenzaldehyde and closely related substrates. Acetic acid serves as the solvent and sole promoter of these transformations which involve dual C-H functionalization.

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with ortho-cyanomethylbenzaldehydes. These amine alpha-C-H bond functionalization reactions are promoted by acetic acid. The resulting beta-aminonitriles can be converted to the corresponding beta-aminoalcohols in diastereoselective fashion.
